Rating: 5/5 Great service June 10, 2016 Eventually got what I wanted. It is quite apparent that these folks take care of their customers. I won't go into the long version of my story, the short version is that the shipping bill was in error and I thought I did not get what I ordered, while in fact, I did. MacSales were great about it and I will certainly not hesitate to order from them again. My only criticism would be the length of time I spend trying to fix my problem online. You guys should hire a few more customer care people. The guy I was dealing with must have been run off his feet.

Rating: 5/5 OWC Memory Just Works! January 15, 2016 I bought 8 GB of OWC memory for my son's MacBook Pro. With help of videos from OWC (which are very good), my son and I installed them. They worked - what else is new? I've bought memory from OWC several times, and every time they worked and I had no problems. I'll continue to buy memory from OWC.

Rating: 5/5 Great experience December 21, 2015 I purchased new memory and a new SSD for an early 2011 MacBook Pro, based on an article I saw. My computer was running so slowly, I was ready to junk it. But after reading that article I decided to try a similar upgrade and for a very reasonable price, my computer runs better now than it did when it was new. (I did double the installed RAM and the old drive was a standard disk, not SSD.)

I found the videos for installing both the memory and disk extremely helpful.

I was considering donating my old computer--now I might just keep it as a backup.

Rating: 5/5 OWC Made my Day ! November 3, 2015 I held my breath, when the mailman put the tightly bound package in my hands. Ha! Ha! was all I could get out when I saw that it contained two exquisite pieces of PC3-10600 DDR3 1333MHz SO-DIMM 204 Pin CL9 SO-DIMM, Memory Upgrade Kit for a total of 8Gb (2x 4GB) of memory for my mid-2011 Mac Mini. No more beach balls, spinning around and around for long minutes at a time,no more slow opening applications or frozen applications, and best of all it had not cost an arm or a leg, like they would have here in Japan. And you want to know the best part? The memory actually has several years of warranty, while here the store clerks look at us bewildered when we ask " How long is the warranty?" Thank you OWC, you guys are great! Plus you are life savers, because I was going to commit tradional Seppuku, if I had another spinning beach ball or frozen computer!
